[Emphasizes the research of diabetic retinal neurons lesions and retinal neuroprotection]

Diabetic retinopathy includes retinal microangiopathy and retinal neuronopathy. Most of the clinical research has been primarily focused on the former. The retinal microvascular lesions and its complications has standardized in diagnosis and treatment. However, the emphasis on the latter has not been attached to the importance in clinic, and it has fewer studies on it. In recent years, studies have shown that the functional lesion of the retinal neurons and glial cells often can be detected earlier than microangiopathy in diabetic patients. Therefore, emphasis on the research of the diabetic retinal neurons lesions and retinal neuroprotection is beneficial to understand the essence of diabetic retinopathy rightly, and has great practical significance in preventing and reversing diabetic retinal neuronopathy in the early stage.
